Prepare a 10- to 15-slide Microsoft® PowerPoint® presentation on statistics and hypothesis testing. For Local Campus students, this is an oral presentation accompanied by a Microsoft® PowerPoint® presentation; for Online Campus and Directed Study students, this is a Microsoft® PowerPoint® presentation with speaker notes.
As a Learning Team, use one of the following StatCrunch data sets from MyStatsLab®:
• Anorexia, as described on p. 383 of Statistics
• FL Student Survey, as described on pp. 22 and 23 of Statistics
• Georgia Student Survey, as described on pp. 22, 23, and 151 of Statistics
• Olympic High Jump, as described on pp. 124, 125, and 128 of Statistics
Each Learning Team must work with a different data set, so check with the facilitator for your data set assignment. Refer to this course’s reading material and at least two scholarly sources from the University Library. Incorporate the following elements into your presentation:
• Introduction
o Introduce the Learning Team members and the data set.
o Briefly explain how the data was gathered and identify the study population.
• Descriptive Statistics
o Define descriptive statistics and list the various descriptive measures.
o Explain how descriptive statistical analysis increases understanding of the data.
o Include an original graph created with StatCrunch that uses at least one descriptive statistical measure to illustrate the data set.
• Inferential Statistics
o Define statistical inference and include and explain at least one original inferential statistical calculation.
o Use StatCrunch to check the calculation and show the steps in your presentation.
o Explain how inferential statistical analysis increases understanding of the data.
• Null Hypothesis Testing

In experimental studies, what is meant by replicating an experiment? Why is it considered desireable?
Describe the different types of data, including nominal, ordinal, interval, and ratio data. Difference among data collection techniques and describe the advantages and disadvantages of each.
TV programs ask viewers to offer their opinions on an issue of the moment by calling a phone number. One program asked viewers whether the International Criminal Court should continue to be located in the Haque. Of more than 173,000 callers, 68% wanted the International Criminal Court out of the Haque. A scientific poll using a random sample of about 400 respondents estimated the true percentage to be 22%.
Differentiate between field studies, surveys, quasi-experimental, and randomized experiments in human services research. Describe each research method and explain how it contributes to the understanding of human services.
A study with 234 low-income alcoholics evaluated the effectiveness of usual care for alcoholics wishing to quit drinking to the usual care enhanced by computer-assisted telephone counseling sessions. Each subject was assigned randomly either to the usual care or the usual care plus counseling, and their drinking status was observed after 3 months. The percentage who were able to quit drinking was lower for the group receiving only the usual care.
